docker-compose搭建nacos单机集群环境

1.配置网络(复用已有网络)

1.1 创建docker虚拟网络

# 创建一个名为tars的桥接(bridge)虚拟网络，网关172.26.0.1，网段为172.25.0.0
docker network create -d bridge --subnet=172.26.0.0/16 --gateway=172.26.0.1 clickhouse

2.启停命令

docker-compose.yml路径下:

构建开启： docker-compose up -d

停止： docker-compose stop

开启：docker-compose start

3. 依赖mysql

• 复用已有的mysql5.7容器，新建nacos数据库，用户。mysql容器启动脚本如下：

sudo docker run -itd --net=clickhouse -e TZ="Asia/Shanghai" -e MYSQL_ROOT_PASSWORD="root" --ip="172.26.0.8" -p 3306:3306 -v /opt/DockerData/mysql:/var/lib/mysql --name=docker_mysql mysql:5.7

• 导入数据表：https://github.com/alibaba/nacos/tree/develop/distribution/conf/nacos-mysql.sql

      MYSQL_SERVICE_HOST=172.26.0.8
      MYSQL_SERVICE_DB_NAME=nacos_devtest
      MYSQL_SERVICE_PORT=3306
      MYSQL_SERVICE_USER=nacos
      MYSQL_SERVICE_PASSWORD=nacos

#登录mysql
mysql -uroot -proot
#创建数据库
create database nacos_devtest;
use mysql;
#创建用户
CREATE USER 'nacos'@'%' identified by 'nacos';
#赋予权限
grant all privileges on nacos_devtest.* to 'nacos'@'%' with GRANT OPTION;
flush privileges;

4. 集群规划

容器ip	端口	节点类型	节点名
172.26.0.130	8848、9555	nacos	nacos1
172.26.0.131	8848	nacos	nacos2
172.26.0.132	8848	nacos	nacos3
172.26.0.8	3306	mysql	docker_mysql，复用已有容器

5. 编写 docker-compose.yml

version: "3.7"
services:
  nacos1:
    image: nacos/nacos-server:latest
    container_name: nacos1
    networks:
      clickhouse:
        ipv4_address: 172.26.0.130
    volumes:
      - /f/DockerData/nacos1:/home/nacos/logs
    ports:
      - "8848:8848"
      - "9555:9555"
    environment:
      NACOS_AUTH_ENABLE: 'true'
      NACOS_SERVERS: 172.26.0.130:8848,172.26.0.131:8848,172.26.0.132:8848
      MYSQL_SERVICE_HOST: 172.26.0.8
      MYSQL_SERVICE_DB_NAME: nacos_devtest
      MYSQL_SERVICE_PORT: 3306
      MYSQL_SERVICE_USER: nacos
      MYSQL_SERVICE_PASSWORD: nacos
    # restart: on-failure
  nacos2:
    image: nacos/nacos-server:latest
    container_name: nacos2
    networks:
      clickhouse:
        ipv4_address: 172.26.0.131
    volumes:
      - /f/DockerData/nacos2:/home/nacos/logs
    ports:
      - "8849:8848"
    environment:
      NACOS_AUTH_ENABLE: 'true'
      NACOS_SERVERS: 172.26.0.130:8848,172.26.0.131:8848,172.26.0.132:8848
      MYSQL_SERVICE_HOST: 172.26.0.8
      MYSQL_SERVICE_DB_NAME: nacos_devtest
      MYSQL_SERVICE_PORT: 3306
      MYSQL_SERVICE_USER: nacos
      MYSQL_SERVICE_PASSWORD: nacos
    # restart: always
  nacos3:
    image: nacos/nacos-server:latest
    container_name: nacos3
    networks:
      clickhouse:
        ipv4_address: 172.26.0.132
    volumes:
      - /f/DockerData/nacos3:/home/nacos/logs
    ports:
      - "8850:8848"
    environment:
      NACOS_AUTH_ENABLE: 'true'
      NACOS_SERVERS: 172.26.0.130:8848,172.26.0.131:8848,172.26.0.132:8848
      MYSQL_SERVICE_HOST: 172.26.0.8
      MYSQL_SERVICE_DB_NAME: nacos_devtest
      MYSQL_SERVICE_PORT: 3306
      MYSQL_SERVICE_USER: nacos
      MYSQL_SERVICE_PASSWORD: nacos
    # restart: always
networks:
  clickhouse:
    external: true

7. 登录ui配置

• 登录 http://127.0.0.1:8848/nacos/ nacos/nacos
• 服务地址：127.0.0.1:8848,127.0.0.1:8849,127.0.0.1:8850
• 开启了鉴权，参考：https://nacos.io/zh-cn/docs/auth.html
